witnessed approximately 1 second of flight of an object unknown to me in the northern hemisphere of the night sky.

this is the first time i have completed a report such as this, but i was curious as to what exactly it was that i saw. the objectwas triangular in shape and had a fuzzy white aura with a green core; it flew east in between the constellations of corona borealis, bootes, draco, and hercules. it then literally disappeared within 1 second; like it slipped into a pocket of invisibility. i was wondering if anyone there either observed the object or picked it up on their telescopes. i just happened to glance at the sky, myself. i wasn't even looking. anyways, i took two college level astronomy classes, i otherwise am always looking up at the sky. i really do not have much experience. but if someone could get back to me with an identification of the object, i would appreciate it. thanks!
